HENRY W. BALTZ, SE, OF PHILADELPHIA, PENNSYLVANIA, ASSIG-NOR OF ONE-HALFOF HIS RIGHT TO JOHN C. GLIME, OF SAME PLACE.

TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 223,979, dated February3, 1880.

Application filed October 27, 1879.

To all whom it may concern:

Be it known that I, HENRY W. BALTZ, Sr., of Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Turbine WVater-l/Vheels; and 1 do hereby declarethe following to be a full clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make to and use it, reference being had to the accompanyingdrawin g, which forms part of this specification, in whicl Figure 1 is atransverse vertical section.

My invention has reference to an improvement on Letters Patent of theUnited States N 0. 214,813, granted to John O. (Jlime, for turbinewater-wheels; and it has for its object the provision of means forobtaining an additional amount of power from the same or required heador flow of water necessary for running wheels constructed according tosaid patent.

My invention accordingly consists in the provision of a turbinewater-wheel placed upon a shaft inclosing a concentric gate providedwith chutes, in combination with another or a second turbine wheelsecured upon said shaft a short distance below that of the first-namedwheel and an intervening fixed chuterin g,

whereby the unspent power contained in the water, as the same issuesfrom the first wheel, will be utilized to give additional power to thewheel-shaft by passing said water to and through the second wheel.

3 5 Referring to the accompanying drawing, A represents the wheel-case,provided with a lid or cover, a, step-bearing B for the step b of theshaft B, and a fixed annular chute-ring, E, which is secured in positionon a shoulder, a

v 4 formed on said case, and is firmly held thereon by means of thescrews a a, or by other suitable means.

a is a water conduit or pipe conducting the water through the opening ain the center of the lid or cover a to the chamber 1), in

which is the annular movable gate D, having chutes d formed therein.Surrounding said gate, audsecuredto the shaft B, is a tur hinewater-wheel, O. Said conduit, chamber,

gate, and wheel are such as are described in the patent already referredto, and therefore need no further particular description, only statingthat the buckets of said wheel 0 receive the impact of the watervertically. F is another or a second turbine wheel, firmly secured toshaft B below the chute-rin g E, and

is formed with buckets ff, so arranged and shaped as to receive theimpact of the water horizontally.

The operation is as follows: The shaft d being turned, the pinion dthereon engaging with a rack on the gate D, as shown, the latter isadjusted to allow the required amount of water to pass through itscontained chutes cl (Z to the buckets of the wheel 0 to revolve thesame. As the water flows off of said wheel 0 it falls into the chamberEupon and passes through the chutes c e of the chutering E, striking thebuckets ff of the wheel F, thereby imparting force to said wheel F toobtain an additional power from the shaft B, which addition in powerwill be nearly equal to the amount of unspent power contained in thewater falling fromthe wheel 0. This unspent power is very considerable,and means which provide for its utilization add greatly to the capacityof the turbine wheels.

I have demonstrated by actual test that a wheel six inches in diameter,whenplaced upon the shaft B in the position shown by the wheel G, will,with a given flow of water, raise a weight oftwenty-one pounds attachedto a rope passing over a ten-and-one-fourth-inch pulley. WVith twowheels, as O and F, placed upon the same shaft B, the wheel 0 being sixand the 5 wheel F nine inches in diameter, and with the same head orflow of water, they together will raise a weight of thirty-four pounds-again of thirteen pounds, or an increase of power equal to over fifty percent. of that obtained by using only one turbine wheel.

What I claim as my invention is- 1. The case A, gate D, shaft B, incombination with turbine wheels G and F and intervening chute-ring, E,substantially as shown and described.

2. The wheel-case A, having central opening,

a, and annular chute-ring E, in combination with gate D and wheel 0,whereby said case In testimony that I claim the foregoing I is formedwith two Water-chambers, D and E, have hereunto set my hand this 14thday of 10 substantially as shown and described. October, 1879.

3. The combination of shaft B turbine wheelsO and F, interveningohute-ring,E,and HENRY BALTZ case A, the latter being formed with ashoul- Witnesses:
